IOException in updateDocument(term, document) method of IndexWriter
Hi,
we are calling updateDocument(term, document) method on IndexWriter and
after that we are calling close() method of indexWriter.
In Close() method i got the following IO exception.
\\server01\files\luceneIndex\_c.cfs (The process cannot access the file
because it is being used by another process)
Ni this case index writer was created successfully and it acquired lock
for that directory and due to above exception the lock file was not
removed.
Is there any chances that _c.cfs file is used by any other process
because index writer already acquires lock on that directory?
Is there any way to handle such scenario ?
Lucene Version : 3.0.2
OS : Windows Server 2003 64 bit
Thanks,
Atul

Hi,
Right now we don't have full stack trace for this exception and this
issue is not easily replicable. We have updated our code to log full
stack trace and once we get this replicated i will post the full stack
trace here.
If anyone have any idea about this then please let us know so we can
investigate it further in that direction.
Thanks,
Atul

Can you post the full exception that you hit?
And maybe a standalone test case showing the problem?

Search Score percentage, Should not be relative to the highest
score
Posted by Amr ElAdawy <Am...@etisalat.com>.
Dear All,
When using lucene to search documents, the results have a score based on their relativity to the search term. Inside lucene, the score
percentage is calculated as a percentage of the maximum score achieved.
Assume we are searching for Amr ElAdawy
We get results like the following along with the score:
Omar ElAdawy --> 1.6
Amro ElAdawy --> 1.9
Amir Adawi --> 1.3
With no exact match. Then the percentage will be calculated relative to the highest score ( despite the fact that it is not exact match). So the percentage will be:
Omar ElAdawy --> 84.21%
Amro ElAdawy --> 100%
Amir Adawi --> 68.42%
I need to change that, so the percentage will be relative to the exact match score. And will be something like that (assuming the Matching result score is 3):
Omar ElAdawy --> 53.33%
Amro ElAdawy --> 63.33%
Amir Adawi --> 43.33%
Regards,
Amr ElAdawy
